My First Grow Journal - Liberty Haze & Gorilla Glue

[DankOfOrmy]

I've just fed my plants and noticed 2 what appear to be deficiencies in the plants on the LH there is a black mark on the end of some of the leaves.

And onthe GG some of the leaves have gone a funny colour.

Any suggestions to what this might be and how to fix it, thanks.

The top one looks like nute burn, the bottom pic looks like magnesium deficiency. The bottom photo looks like serious heat/light burn going on too

 

[DankOfOrmy]

What do you mean by nute burn? I have just given it some cal mag, I forgot to give it some last time so that'll be why for that however for the light burn the lights haven't changed at all they are still 400w and on the same cycle at the same distance

 

[Pennywise]

Do you water to run off?

 

[DankOfOrmy]

When they were in smaller pots I did however when I moved them to bigger pots I didn't as I didn't want to over feed them, I gave them more nutes and water but there isn't always a run off, I just checked them then and there is a run off on the LH but not on the GG

 

[Pennywise]

Make sure you're watering fully, whats you're ph looking like

 

[DankOfOrmy]

Well my ph tester goes up in .5's so it varies from 6-6.5

 

[Pennywise]

Need to test your runoff water for ph, Mag is locked out and its showing nute burn.

 

[DankOfOrmy]

How do I test the run off water?

 

[Pennywise]

Run water through the pot and collect runoff water then test that.

 

[DankOfOrmy]

Right so I've just taken a few tests and I'm really confused, so the oh level of the water and nutes was 6-6.5 the ph level of the soil is looking at 5.0 for the LH and for the GG 4.0 and the run off appears to be for LH 5.0 and GG 5.5, tbh I'm not entirely sure if this is normal or not but the readings don't seem right to me and I am really unsure as to why this is having readings of 4.0 in the soil???

 

[Pennywise]

You need to bring that ph up, run 6.5 ph water through it until the soil ph comes up. Use a weak nutrient solution.

 

[DankOfOrmy]

Do you mean when I feed it just keep giving it 6.5? Or do you mean run it through now? And what do you mean by weak nutrient solution, apologise if it's obvious this is my first grow so I'm still getting to grasp with it all

 

[Pennywise]

Mix up your nutrients at 1/4 strength then ph to 6.5-7.0 and run a lot of water through the pot. It should bring up your soil ph. You can start raising the nutrients with your next feeding. Id flush it now

 

[DankOfOrmy]

I've already given it nutrients today which is when I noticed it, the current mix is 4ml bloom and 1ml cal mag so I'll use 1ml of each next time, and I've already flushed using water so what I'll do is next time I water which will be in a few days I'll set the ph level to 6.5/7 and let the water run off then and will do the nutes probably this time next werkc

 

[Pennywise]

Ok but you need to raise that ph soon. The nutrients are locked out and your plants cant use any of them.

 

[MiOutdoorsman]

How's the plants Dank

 

[DankOfOrmy]

The plants are still the same the deficiency looks like it's still there and getting worse, I've been raising the ph level of the water to 7.0 and giving it that it's had 2 water feedings since last week as it seems to be drying out a lot quicker they're getting nutes tomorrow, and I will upload some pictures later when I'm home

 

[DankOfOrmy]

GG

LH

As I say I've been doing the feeding as you've said and the run off has raised to 6.0 so I'm really unsure as to why they're still as they are and getting worse... really really concerned

 

[DankOfOrmy]

These are what some of leaves on the GG however they're only on what I think are the fan leaves? Really really confused
